Are Aliens Visiting Earth?

[Measure_for_Measure]

Right, but drop said monk in a city, or anywhere with a clear view of human habitation, and he would appreciate the evidence of a TI (terrestrial intelligence). And that’s exactly the point. We don’t see anything, period.

Monk couldn’t perceive alien intelligence in the sky any more than we can. Sure we have orders of magnitude better devices. But what they can rule out is… modest. Thread: SETI research: what can we now rule out?
